8.12.3 Defining the path for OEM tables

8.12.4 Symbolic names for tables

January 2012

Use the machine parameter MP_oemTable to define the path for OEM tables.

OEM tables include tables such as the *.CMA and *.COM compensation-

value tables for axis-error compensation or the *.MOT OEM motor table. With

MP_oemTable, you inform the control about the location where the OEM

tables are stored. The default setting %OEM%\table is entered in the

Path for OEM tables

Available from NCK software version: 597 110-01.

For access via SQL commands, tables are identified with a symbolic name and

a file name including the path for the table characteristics.

Direct use of these paths, such as from cycles, has the disadvantage that if

the drives or paths are changed, or if other tables are selected, the cycles must

In order to avoid this disadvantage, symbolic table names are used. These

table names are place holders for the actual table name and path. When

accessing a table, the control replaces the symbolic table name with the real

table path and name.

Symbolic table names are saved in the control's configuration data in the

CfgTablePath object (new key name). A symbolic table name should consist

only of capital letters.

The logic names do not have to be in any certain format. Any name can refer

to any table or table type.

The table being referenced does not even have to exist at the time that the

logic table name is given. It can also be created afterwards.

Proceed as follows for specifying a symbolic table name:

Enter the code number 95148.

Press the CONFIG DATA soft key.

Select the System/Paths/CfgTablePath object.

Press the INSERT soft key.

Enter the symbolic table name (key name) and the storage file (e.g. the file

PLC:\config\oemtable.cfg) and confirm with OK.

Define the storage location of the table in MP_path.

Press the SAVE soft key to save the data.
